Determination of reliability indices of the distribution network based on data from AMI

Abstract

Improving reliability of a power network is an issue of great importance for power distribution companies. The aim stated by the President of Energy Regulatory Office to improve the reliability of the distribution network includes steps towards improving the monitoring and control of the network managed by distribution companies. Ensuring continuity of energy supply is one of distribution companies’ duties and one of the criteria used to assess the effectiveness of network operation. Distribution companies all over the world employ indices SAIDI, SAIFI and MAIFI to determine mean values concerning the number of time of interruptions per consumer in a year. The paper deals with methods of correct and precise determination of the values of the reliability indices SAIDI, SAIFI and MAIFI by means of the application Advanced Metering Infrastructure in the distribution network.
